Abstract
Disclosed is an electronic appliance, for example such as an electronic musical instrument, having a secondary storage device for storing data to be recorded which can be easily divided into divisional elements under a plurality of predetermined items. With respect to information to be stored in the secondary storage device, a portion the same as the already stored information is not newly stored to thereby effectively use the storage capacity of the secondary storage device. In the electronic appliance, specifically, data to be stored as one file in the secondary storage device is divided into a plurality of constituent portions under predetermined items, file names are affixed respectively to files, and entry names are affixed respectively to the itemized constituent portions. A file to be newly stored is divided into a plurality of constituent portions under the predetermined items and a judgment is made as to whether any of the constituent portions of the new file is the same as any of the already stored constituent portions of the other file with respect to one and the same item, so that the same entry name is affixed to the same constituent portion without storing the contents of the constituent component in duplication so that the same data is used in common to a plurality of files.
